Preferably the embodiment of my invention but it will be shape of the anchor bar is suchthat it can be 45 understood that this particular embodiment readily inserted through the openings in the has been chosen for the purposes of illushousing. In the present instance, a portion tration only and that the device may take 10 of the anchor bar, which projects beyond various forms and may be used in various one side of'the housing, is bent rearwardly at ways without departing from the spirit of an acute angle to the intermediate portion of 59 the invention. r the bar so as to provide a relatively thick por-' tion of concrete between the same and the front surface of the concrete structure. The other end portion 11 of the bar extends a short distance beyond the. other side of the housing and is then bent rearwardly. VA sup-v porting member or finger 12 extends laterally from the rearportion of the housing and en:

The device for attachingthe angle bar to the anchor bar may takev a'riousiforms but is preferablyin the form of a bolt, 18 and is provided with means whereby it, may be connected with the anchor bar atIdifi'erentpost tions within the housing or cavity, so that the outer end: of the attachingdevice may be adjusted with .relationto the concrete structure in roperly position the same. The bolt here' shown has at its inner 'end a hook shaped portion 14L of such a character that itmay be hooked about and engaged with the intermediate" portion of the anchor bar and maybe out the, width of the cavity and may also be moved about the axis of the anchor bar so that the outer endthereof, whichfproj 'ects beyoiid the open side of the cavity, may be Q raised orlowered. In'this'manner the bolt is. provided withia relatively large range of adjustments to accommodate it to the positionfoftlie bolt hole 15in the angle-bar 7..
